Kolliker can be seen in specimens stained by Van Gieson's method,, 

 and the lumina of the rich plexus of arterioles, venules and capillarie? 

 that surround the duct are often seen in cross-section. Ducts of the 

 first order present no characteristic differences from those observed in 

 the Ductus submaxillaris, except that the connective tissue which em-

Fig. 5. — Sections of a Tmri\<m siibmaxiUari/ gland stained by Henson''s modiflcation of 

 Van Gieson^s stain. Magnified about 85 diameters. This section shpws one of the 

 interlobular spaces with the duct and its vasa comites. Adjacent lobules show the 

 mucous and serous portions of the gland. D, Interlobular duct ; T", Interlobular

 This connective tissue is continuous with that which enters the gland 

 at the hilus and forms the main support of the glandular lobules. The
